Identification Codes for Listed Wastes

Each list contains from thirty to several hundred hazardous wastes. Each waste on the lists is assigned a unique identifying code. This code consists of the following:

Letter of the list that contains the waste (F, K, P, or U)
Identification number (for example, a waste code)

It is important to become familiar with these codes, because the management standards differ according to a waste's code. Next, we will take a closer look at each of the lists of waste.
